 <p>Configure the inspection:</p>
 <p>Use the <b>Minimum number of branches</b> field to specify the minimum expected number of <code>case</code> labels.</p>
+<p>Use the <b>Do not report pattern switch statements</b> option to avoid reporting switch statements and expressions that
+have pattern branches. E.g.:</p>
+<pre><code>
+  String result = switch(obj) {
+    case String str -> str.trim();
+    default -> "none";
+  };
+</code></pre>
+<p>It might be preferred to keep the switch even with a single pattern branch, rather than using the <code>instanceof</code> statement.</p>
